How to prevent url to show in web view

Question

Hi there I am trying to create app where I am using web view to show my google drive folder but whenever internet got disconnect in between loading the URL at that a msg comes with showing the URL information. What can I do to prevent showing URL from users. Is it possible to show some other msg whenever internet goes down on starting or when it goes down on after starting loading.

Answer 1

I have a custom HTML page that will show if something wrong happened when loading the url.

webView.setWebViewClient(new WebViewClient(){
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        switch(errorCode){
            case ERROR_HOST_LOOKUP:
                webView.loadDataWithBaseURL(null,"<YOUR OWN CUSTOM HTML PAGE TO SHOW WHEN THERE'S AN ERROR>", "text/html", "UTF-8",null);
                break;
            case ERROR_CONNECT:
                webView.loadDataWithBaseURL(null,"<YOUR OWN CUSTOM HTML PAGE TO SHOW WHEN THERE'S AN ERROR>", "text/html", "UTF-8",null);
                break;
            case ...[IF YOU WANT TO CATCH MORE ERRORS]
        }
    }
}
